Answer to Question 1

Ans:
A

Feedback:

Because they do not normally divide, neurons do not undergo hyperplasia. Remaining organs can display hypertrophy, not hyperplasia, and prostate enlargement is a form of hyperplasia. Cardiomyopathic hyperplasia involves greater increases in cell length than width.

Answer to Question 2

Ans:
B

Feedback:

This patient exhibits several classic signs of Marfan syndrome, an autosomal dominant genetic disorder of the connective tissue. The other patients show signs of heart disease most likely caused by multiple factors.
